VACCINE-SHIELD.

SPECIFICATION forming part of Letters Patent N 0. 729,293, dated May 26,1903. Application filed August 21, 1902 Serial No. 120,466. (No model.)

To all whom it may concern:

Be it known that I, ALBERT B. DORMAN, a citizen of the United States,residing at Winthrop, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inVaccine-Shields; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to shields for protecting the arms of patientswho have been vaccinated; and it consists in the novel construction ofthe shield, as hereinafter fully described and claimed.

In the drawings, Figure 1 is a plan view of the shield. Fig. 2 is asection taken on the line a; w in Fig. 1.

A is the shield, which is provided with an oval rim 1), concavo-convexin cross-section and curved upwardly atits ends. The shield is providedwith curved cross-bars c, which extend between the rim and which arearranged at right angles to each other, leaving large openings dadjacent to the rim. The central portion of the shield is provided withadditional curved cross-bars e, which form smaller openings f. Slots 9are formed in the rim 1) for the insertion of bands or strips ofadhesive material for holding the shield in position on thearm of thepatient.

The oval and curved shape of the rim enables it to fit against arms ofdifierent size. The shield is made of aluminium, and it is easilycleaned and sterilized. The openings expose the vaccinated area to view,and the shield never chafes the parts.

This shield is superior to shields made of adhesive plaster andtransparent material and which are nearly air-tight, as it never heatsor steams the parts and always allows suificient ventilation.

These shields are used with an antiseptic gauze dressing or two or threeturns of a gauze 5 bandage over them or not, as is thought best by theattending physician.

What I claim is-- A vaccine-shield of thin sheet metal, provided with arim which is oval in form and concavo-convex in cross-section, fourcurved cross-bars 0 extending at right angles to each other between therim and forming four large openings (1 adjacent to the rim and four vsmaller triangular openings, two cross-bars e at the central portion ofthe shield which form four small openings and slots 9 formed in the rimparallel with its edge, substantially as described and shown.

In testimony whereof I afflx my signature in presence of two witnesses.

ALBERT DORMAN.
